Description
The Transiting Exoplanet Survey Satellite (TESS) was primarily designed to monitor stellar light curves and detect exoplanets. However, its full-frame images (FFIs) could be valuable for studying low surface brightness objects. In this work, we construct a full-sky map from TESS image patches in HEALPix format with a pixel size of 1.7'×1.7'. To enhance the usability of the map for extragalactic studies, we remove about 4 hundred millions foreground stars detected in Gaia. The resulting map provides a powerful tool for stacking analyses of extended structures beyond the Milky Way, including galaxies, galaxy clusters, and large-scale structures. This map offers new opportunities for exploring faint astrophysical phenomena at large scales.
